Output efficiency of research university in China (2000-2015): Based on the SBM of super-efficiency DEA model and global malmquist index analysis

In this article, the input-output efficiencies of China research universities from 2000-2015 was analysed based on SBM of Super- Efficiency DEA model and Global Malmquist Index, Results show that the mean score of efficiencies during the 15 years is generally on a continuous increasing trend, featuring scale expansion and structure optimization of output To be specific, comprehensive universities and universities of science and technology show similar trends: The efficiency score increases significantly from 2000 to 2005, while the increasing rate is slightly lowered from 2010 to 2015; the efficiency score of universities of humanities and social science is the lowest among the three types of universities, however, its efficiency score is generally in increasing trend.
